Kabbalah Yesaya 45:17: Sha'arei Orah

This is why in the Rosh HaShanah prayers it was established to recite, “It is incumbent upon us to praise the Master of all-Aleinu L’Shabei’ach-עלינו לשבח.” If you contemplate the words of this prayer, you will discover that the matter of the seventy nations, which are the seventy families of the children of Noach, is mentioned in it. It therefore mentions “the nations of the lands,” and, “the families of the earth.” Now, the statement there that,²⁰⁹This is the continuation of the Aleinu prayer in the Sefardic tradition. “They pray to a god-El-אל who cannot save,” does not refer to the Almighty God-E”l-א״ל, but to their ministering angel. That is, though all their ministers are called mighty-El-אל because of their greatness and level,²¹⁰That is, the title Mighty-E”l-א״ל is a shared titles that is also used in regard to angels and created beings, as in the Talmudic dictum (Gittin 60b), “Whoever is mightier prevails-Kol d’Alim Gvar-כל דאלים גבר,” or like the Talmudic statement (Kiddushin 59a), “A valley of strongmen-B’Aga D’Aleemay-באגא דאלימי.” Similarly, this terminology is found in Psalms (58:2), which states, “Is it so that (you) mighty-ones (Ailem-אלם) speak righteousness?” See Ginat Egoz of Rabbi Yosef Gikatilla, translated as HaShem Is One, The Gate of The Title (Shaar HaKinuy), at greater length. they nonetheless are unable to save. For none can either add or subtract from what was apportioned to him on Rosh HaShanah. For, the angelic minister of each nation himself looks to the portion apportioned to him from the House of the Great King, HaShem-יהו״ה, blessed is He, just like all other deficient beings in the world, and he too only receives his portion. Therefore, he certainly “cannot save,” for there is no salvation except in the Name HaShem-יהו״ה, blessed is He. This is the meaning of the verse,²¹¹Isaiah 45:17 “Israel is saved through HaShem-יהו״ה, an eternal salvation.”
